SPECIFICATION forming part of Letters Patent No. 320,377, dated June 16,1885.

(No specimens.)

To aZZ whom it may concern.-

Be it known that l, JEAN A. lVIATHIEU, of Port Leyden, in the county ofLewis and State of New York, have invented a new and useful Improvementin Baths for Electro-Deposition of Nickel, of which the following is aspecification.

My invention consists of a process of electrodepositing nickel by meansof a solution of propionate of nickel.

To make the bath I make a solution of propionate of nickel, either bydissolving oxide of nickel in propionic acid or in any other way ofattaining the same result.

The articles to be plated with nickel are prepared and placed in thebath in the manner now commonly in use, and an electric current ispassed through the bath in the ordinary manner. The solution gives bestresults at a strength of about 5 Baum. Any regular electric current willanswer in the process;

but a current from a dynamo is preferable, and the strength of thecurrent may Vary.

I do not claim in this application anything" JEAN A. MATHIEU. Witnesses:
